Abstract :
The previously proposed delay-dependent robust stability criteria of a class of uncertain mixed neutral and Lur´e dynamical systems with interval time-varying delays are refined by eliminating nonlinearity and reducing the number of free-weighting matrices. Several robust stability criteria proposed in this paper are simpler and effective. Numerical examples show that the new method is less conservative than some previous approaches.
